摘要

本文介绍了太空应用固体润滑涂层的实验研究结果，特别是最有效的涂层之一 EONIT-3。根据接触压力、滑动速度、压头-圆盘和轴-套筒测试模式，研究了涂层在零下 150 到正 400 摄氏度的空气和 10-6 毫米汞柱真空条件下的摩擦系数和耐磨性。结果表明，在摩擦化学过程中，二硫化钼这种主要的工业固体润滑剂起到了活性催化剂的作用。在 200°C 下经过两小时热处理后，EONIT-3 涂层的抗摩擦性和物理机械性能达到最佳且稳定。

Tribotechnical Characteristics of Solid Lubricating Coatings

The results of experimental studies of solid lubricating coatings for space applications, in particular, one of the most effective coatings EONIT-3, are presented. The coefficients of friction of coatings and wear resistance at temperatures from minus 150 to plus 400°C in air and in vacuum 10^–6 mm Hg were studied for various combinations of antifriction materials depending on the contact pressure, sliding speed, indenter—disk and shaft—sleeve test patterns. It is shown that in tribochemical process molybdenum disulfide, the main industrial solid lubricant, plays the role of an active catalyst. Optimal and stable antifriction and physico-mechanical properties of the EONIT-3 coatings are observed after two hours of heat treatment at 200°C.
